As of November 2014, IDMC estimates that there were 334,000 internally displaced people in Yemen, most of them located in the country’s north.

IDMC bases its estimate on figure made available by the UN Agency for the Coordination of Humanitarian Affairs (OCHA) which is in turn derived from the number of IDPs registered by the Government’s IDP Executive Unit and UNHCR as of 30 September 2014 (OCHA, 7 November 2014).

Joint IDMC-UNHCR press release - A record 33.3 million now displaced by war worldwide, as one family flees inside Syria every 60 seconds - Report

33.3 million people were internally displaced at the end of 2013 due to conflict and violence says a new report by the Internal Displacement Monitoring Centre (IDMC). This equates to a staggering increase of 4.5 million from 2012, signalling a record high for the second year running.

28.8 million internally displaced people worldwide in 2012, record high includes five-fold increase in Syria

GENEVA, 29 APRIL 2013: The number of people internally displaced by armed conflict, violence and human rights violations at the end of 2012 was 28.8 million, an increase of 2.4 million people on the previous year and the highest global figure ever reported by the Internal Displacement Monitoring Centre (IDMC).

For the last 14 years, the Norwegian Refugee Council’s Internal Displacement Monitoring Centre has monitored intern- al displacement resulting from conflict and violence across the world. In 2011, the number of people internally displaced by these causes stood at 26.4 million.

In the wave of civil protests which have swept across the Middle East and North Africa, political instability and increasing violence involving the Yemeni government, protestors, rival tribal militias and militants have led to new waves of displacement in southern, central and northern areas of the country.

Following intermittent clashes between
Al-Houthi groups and the Yemeni government in July 2009, the situation
in Sa'ada governorate escalated into open conflict in the sixth round of
hostilities since 2004. Tens of thousands of people were displaced from
Sa'ada and Amran governorates, adding to those displaced by previous rounds
of fighting. For many, it was their second or third displacement over the
last few years.

In February 2010 a ceasefire put an end
to hostilities; however intermittent violence has continued in affected
governorates.

Fighting between government forces and
followers of the late Sheikh Badr Eddin al-Houth have led to displacement
in northern Yemen at regular intervals since 2004, peaking during the latest
round of conflict in June and July 2008. Though many returned to their
places of origin following the end of hostilities in July 2008, large numbers
were unable to return home.

An estimated 100,000 people remain internally
displaced as result of the Sa'ada conflict, including some who have gone
back to places of origin.
